Anyone else have to deal with parents “getting busy” while on the clock?

Welp title says it all… unfortunately not the first time both parents sneak up stairs while I’m home with the kids. I ran upstairs to grab something for the kids and very obvious what’s going on 😬

Like I get it, someone’s watching them for you but wouldn’t you think they’d feel awkward? Or do they just think I’m dumb lmfao
